Application tiled April 29,

.To aller/10m it may concern:

Be it known that l, HARRY LANDSIEDEL, a. citizen of the United States, residing at Poplar Bluff, in the county of Butler and State ot- Missouri, have invented new and useful li'nprovements in Adding-Machines,

ohine, and the present invention includes,

in combination with the machine and the motor, automat-ic mechanism to' cut oil the power by which the motor is driven and thereby stop the motor.

-An object vof the present invention is Oto provide improved mechanism whereby the running of the motor may be stoppedautomatically, after a suitable interval, when the machine is left idle and inoperative. Another object is to provide means, controlledhjyfvt'he motor itself, for cutting off the power Yof the motor so that themotor will he stopped, after a suitable interval., when the machine is idle.

i'lther objects will appear from the following description, reference being made to the accompanying drawings in which l have illustrated my invention combined with a Daltoiradding machine and the motor for operating said machine.

The adding and recording mechanisms' of the Dalton adding machine are viiotlillustrated in detail in the accompanying ,d raiv--` ings vbecause it is notfessentialI vthatg-said` mechanisms be completely illustrated.4ingorder to understand the nature and. pi pose and mode of operation 'of the 'presentimiention. The' adding and recording meelllaf;n

nisms are controlled in theirfoperationspby a rock shaft 1 supported in bearings ivi h' the case of the machine. ,When itisdesired to operate the adding and recording mechanisms, the rock shaft 1 is rocked in one'vdifi,

rection against the tension of .springs 2, which are engaged with some portion ofthe frame of the machine and also with anarm or lever. 3 attached tothe rockshaft; Vllien the adding and recording mechanisms l I i completed their movement and .the rock shaft 1`fis released, said shaft is returnedto its idl or rnormal position, as shownl inv 1g- 1, by the power of the springs 2.

direction and then release the said shaft so thatithe power springs 2 may restorosaid shaft and the other parts to their idleposi tions. An arm or lever't, whiehmay `bel'a part ot'thearm or lever 3 or separatethere` from as desired, extends through .slot

the base o f the machine and is arrangedlso that it will be engaged by 'inleven-Leontrolled liv theI motor. f The operation ofthe le'rcr 7, which is pivotally supported -at.f,8, operates the lever G effectively to rockgthe= shaft l in one direction, and is releasedfrom said lover at the end of its stroke sothat thi` power springs 2 will rock the said shaft l in 'the opposite directionfto itsidleor normal position. The lever-'Tis returned, to. idle position after eal'h movcmentot*the motor, lliv a spring 9.

The motor 5 is a rontiuuouslvrunning motor androtats a shaft l0 on whichis'a worm 11, (Fig. 2). The Worm 11 is in'con stant mesh with a wheel 12 loosely mounted on a shaft 13, so that said wheel l12 will be in constant and rapid rotation when the motor is running. A disk 14 having notches forming teeth on its periphery is attached to and rotateswithy the wheel 12. A support 15 is attached to the shaft 13 and carries a latch device 16 which is normally held out of engagement with the disk 14 by means of suitable connections 17 which do. not require s ecific description in this specification for t e reason that said connections are not specifically claimed herein, and for the further reason that said connections constitute a part of the subject-matter of a copending application. It is obvious that when the motor is running, the wheel 12 and disk 14 will be in constant and rapid rotation and if the latch device 16 be engaged with the disk 11 the shaft 13 will be rotated until said latch device is released. In or near the key-board of the machine, (Fig. 1) a key 18 is mounted and is provided with a train of connectionsi) whereby the latch device 16 may be caused to engage with the disk 14. The shaft 13 has on one end thereof an eccentric disk 20 which, when rotated, rolls against a lateral. extension 21 on the lever 7 electively to operate and cause said lever to engage the ilever 6 and rock the shaft 1 in one di-rection in opposition to the power of the springs 2 and thereby permit the adding and recording mechanism of the machine to operate to perform their various functions. The motor 5 is controlled by switch mechanism 22 which may bev of any suitable or wcll known ty e, and which may be thrown on or o as desired, by pressing inwardly the buttons 23 and 24, respectively. That is to say, When the button 23 is pressed inwardly the ower will be turned on and the motor will be operated, 'and the shaft 1 may be intermittently rocked las the result of the manipulation the key 18 as above explained. By pressing .inwardly theI button 24, however, the power Y; ill be turned f off and the motor will be stopped, The subject-matter of the present application comprises mechanism controlled by the motor and a part of the devices above described, for operating the switch 22 to turn the ower oil, after a suitable interval anc as an incident to leaving the adding and recording mechanisms idle.

Should the operator'be called away or leave the machine without operating; the switch to turn oli' the power, this desirable result will 4be effected automatically by my invention, However, 'if the machine is operated at frequent intervals the power will not be cut oil as this would .be the occasion of considerable inconvenience. My

invention, therefore, includes mechanism or devices, operated Incidently to each. operation of the devices which rock the shaft 1, to disable or cause to return to idle position the mechanism which controls the switch. The wheel 12 carries a pin 25 which, at each revolution of the wheel 12, engages a disk 26 rotatably supported upon a stud 27 In this way the disk 26 will be turned the distance of one tooth at each revolutionof the wheel 12 and locked against accidental rotation.

At the side of, and rigid with the disk 26 is a disk 29 having a single tooth or projection 30 on its periphery. A disk 31 of a construction similar to the disk 2 6 has itsy teeth extending close to the periphery of the disk 29 (Fig. 4) so that said disk 31.-

will be locked against rotation untilturned the distance of one tooth at each revolution oi the disks 26 and 29. Therefore, since the disk 26 is turned the distance of only one tooth for each complete revolution of the wheel 12, and since the disk 31 is rotated the distance of only one tooth for each complete revolution of the disk 26, it is clear that the wheel 12, which is'driven by the motor shaft 10, will make a large number of revolutions before the disk 31 will be turned a complete revolution. Thus the dill'erential gearing which is locked against accidental rotation by the wheel 12 is also driven or rotated by 'the wheel 12.

The disk 31. is rigid on a stud 32 which projects through the housing or case inclosing the mechanism last described and has on its outer'end a crank A pawl carrier 34 is slidably supported by the case or housing for the mechanism, studs 35 extending through slots in said pawl carrier and permitting longitudinal movement thereof. The crank 33 extends into a vertical slot in the pawl carrier 34 so that said pawl carrier will be slowly reciprocated longitudinally whenever the motor is running, the train of differential gearing from the wheel 12 constituting the mechanism for reciprocating pawl carrier.

A T-shaped lever 37 is pivoted upon a support 38 close to the switch buttons 23 and 24 andlis operable to actuate said switch buttons to control the switch and turn the power on "or oft A. link 39 connects the stern of the lever 37 with one arm of a. bell crank lever 40, the opposite arm of said bell crank lever having pin and slot connection 41 with a sliding actuator 42.
